| Summary: | 碩士 === 國立中正大學 === 國際經濟所 === 98 === This study aims to establish a framework of Knowledge Structure-based Computerized Adaptive Test（KSAT） in Economics. In addition to being able tosave test items and reduce test time, student’s test results under this framework can provide instructors a basis for remedial instruction. This study, using the KSAT system, also intends to investigate which types of exam questions fit better for students and to probe into the teaching goals specified in the “99 Course Outline: Economics”circulated among vocational high schools in Taiwan.
This study first constructs an instructor''s knowledge structure of the "Demand" unit and builds up test questions based on this structure. Paper-pencil tests are then performed by 300 students and test results are analyzed. These results are input into the KSAT software system to trace out students’ knowledge structures. Finally, the computerized adaptive tests are applied to a different group of 340 students and results are analyzed. KSAT testing results so generated will serve as guidelines for teachers to prepare their test questions and to impose remedial instructions.
Major findings of this study include:
1.The KSAT system designed in this study can replace traditional paper-pencil test without any errors. It provides an accurate instrument to diagnose student’s misconceptions. In addition, it indeed retrenches about 28% of test question and reduces huge amount of test time accordingly.
2.Test results show that the correct response rate of "application" questions is the highest, followed by "concept" and "understanding cum analysis", and the last is "graphic interpretation". This outcome is distinct from the teaching goals specified in the “99 Course Outline: Economics”, which intends to provide logical training and quantitative analysis ability to vocational high school students.
